Miller Balancing Resistor

Hello I have an older Miller 330ABP TIG welder and have thought of bypassing the Balance Resistor , the resistor is made up of monel bands that are in series with the terminal block or torch electrode , resistor is only used in the AC mode , also use a Miller Syncrowave 350 , it also uses a ceramic wire wound in series with AC only , would make fan on demand retrofit much easier if these resistors could be eliminated, have been Advanced Class Ham operator for many years , if I could understand the need for them it might help. Thanks Phil L.
